Chukka is bladder dock, a sour, slightly fleshy leafy green cooked across Andhra Pradesh and Telangana as chukka koora and in Tamil homes as chukkan keerai. Its sharp lemony taste comes from oxalic acid, so a handful sours a dal without tamarind. The name bladder dock refers to its papery, inflated pink fruits. It is a garden and market green, not sorrel from a European tin.

How to recognise Chukka
It is a low, branching annual, usually under knee height, with smooth, slightly succulent stems.
The leaves are pale green, soft and fleshy, broadly oval to triangular, on long stalks.
Tiny greenish flowers grow in small clusters along the upper stems.
Each fruit is wrapped in enlarged, papery, net-veined wings that turn pink or red and look like small bladders.
Garden sorrel, Rumex acetosa, has longer arrow-shaped leaves and much smaller fruit wings.

Modern notes on Chukka
The sour taste comes mostly from oxalic acid, which is also found in spinach and sorrel.
Like other leafy greens it supplies vitamin C, folate and fibre when eaten fresh.
Cooking reduces soluble oxalate somewhat, especially if the cooking water is discarded.
Chukka safety
People with kidney stones or advised to limit oxalate should eat it only occasionally. Cooking it with dal and calcium-rich foods such as curd lowers how much oxalate the body absorbs.
Ecology and sourcing
It is native from North Africa through the Middle East to India.
It tolerates heat, sandy soil and some salt, so it springs up after rain in dry regions.
In gardens it grows from seed in a few weeks and is ready for cutting quickly.
